I have a Nook Classic ... I love it ... mostly. I'd like a built in light and I know newer readers are smaller and lighter in weight.

I like that I can read just about any e-book file except the Kindle.

I looked at my mom's Nook STR (non-glow) and, while I liked the overall feel and user environment, I simply couldn't stand the library organization. It makes SO much more sense to select a book and then choose what shelves it belongs on rather than pick a shelf and wade through 200 books to find the book you want ... ugh!

I looked into Calibre, but I really like the idea of doing the library management on the device rather than the computer ... when I finish a book at the drs office, I'd like to move it to "finished" right then.

So, now I'm looking at the Kobo Glo .... I can sideload my B&N books on it, correct?

The one thing that trips me up is the page refresh ... maybe I'm dense here, but I read for hours on my Nook and I've never noticed a screen flash except when changing screens ... like after choosing a book to open or when it goes to sleep. I've seen a video of the Kobo Glo in action and the screen flash seems very distracting.

So .... I'm looking for eInk, touch, built in light, a library management that allows me to define shelves (or collections or whatever they are going to call it) in a logical manner ... select a book and select the shelf (or shelves) it belongs on. and preferably decent battery life ... I charge my Classic twice a week. (w/Wifi off).

I want to be able to read B&N books, library ePubs, secure e-reader files (from Fictionwise), and pdfs. I don't mind sideloading everything ... 2/3 of what I have on my Nook Classic are non-B&N books.

After watching the Kobo Glo video again, and turning pages in my Nook, i realize it DOES flash after each page turn ... so I think if the Kobo can read B&N books and the library structure isn't dumb, that may be the way for me to go ...

There were a ton of complaints about the Nook Glowlight's screen breaking too easily, so I would definitely recommend you do a google search for that before investing in one, if that's what you will end up deciding on.
Apparently, the light layer breaks even the device is carried around in a sleeve, and once that film is broken, it is impossible to read on it.
